Hello, this is a known problem without a fix. Ive contacted support multiple times but they seem to not know how to fix this. I even made a video
Only way I can play is joining a low pop server like 40/80.

BUMP
This problem is still present. I even made a video about the issue and contacted support on many occasions but they seem to be oblivious on how to fix it.
I also tried to use the DNS change but it never worked... as Mendes said, it works when we join a server with low pop like 40/80.
